1/2 and 3/4" Two-Way NO
Pressure Independent Control Valve.
Pressure Independent Control Valve.
Description
The 1/2- to 1-1/4-inch normally closed and 3/4-inch
normally open Pressure Independent Control Valves
have a 5 mm stroke, and work with the SSD Series
Electronic Actuators. The 1/2-inch normally open valves
have a 2.5 mm stroke and also work with SSD Actuators.
The 1-1/2 to 2-inch valves have a 6.5 mm stroke, and work
with the SQD Series Electronic Actuators. The actuators
require a 24 volt power supply to provide oating or
0 to 10 Vdc control.
Typical applications include control of hot or chilled
water or water-glycol solutions up to 50% in closed
loop systems.
Features
• Control valve with integrated pressure regulator
and adjustable ow limiter
• Direct-coupled, universal bonnet
• ANSI Class 250 valve body
• ANSI Class IV leakage @ 200 psi (1/2 and 3/4 inch)
normally open valves
• ANSI Class IV leakage @ 45 psi (1/2 to 1-1/4 inch)
normally closed valves
• ANSI Class III leakage @ 50 psi (1-1/2 to 2-inch)
normally closed valves
• Linear Flow Characteristic
• Brass trim with stainless steel stem
1/2 to 1-1/4" Two-Way NC
1-1/2 to 2" Two-Way NC
Pressure Independent Control Valve.
Applications
For use in HVAC applications with the Pressure
Independent Control SSD or SQD Electronic Actuator, to
control hot or chilled water or 50% water-glycol solution in
closed loop systems.
